Title: Successive apporoximation a/d converter
Inventor: KAWASEKI MASAFUMI
IPC: H03M1/38
Filed: 1993-09-13
Abstract: PURPOSE:To improve conversion accuracy by reducing the fluctuation of converted data by sampling and counting the output of a comparator with the N-times clock of conversion time. CONSTITUTION:When inputting a second analog signal 16 at a fixed level, data for first comparison are set from a control unit 4 to a register 2 and sent to a D/A converter and a counter 5 is reset. A first analog signal 15 is inputted from the D/A converter 1 to a comparator 3 and compared with the second analog signal 16. In this case, when the output of the comparator 3 is fluctuated, at timing to fetch the compared result into the register 2, the output of the comparator is turned to the instable state of '1' or '0'. When probability to be '1' is defined as 6:4, for example, the output turns '1' at the rate of 60%. Therefore, when sampling is performed five times in one time of conversion, the output turns '1' at the rate of 74% in terms of calculation, and the fluctuation of data can be reduced.

IPC: H01Q5/10
Filed: 1998-08-10
Abstract: PROBLEM TO BE SOLVED: To make the system and device small-sized and lightweight by providing a 2nd dielectric which is formed on one surface of a radiation conductor and a 2nd ground conductor which is formed opposite to the radiation conductor across the 2nd dielectric and short-circuited to a ground conductor. SOLUTION: The capacity can be increased by forming a plate type inverted F- shaped antenna in two-layered structure wherein a 1st antenna is formed of a radiation conductor 52 and a ground conductor 51 short-circuited by a plate type inverted F- shaped short-circuit conductor 14 and a 2nd antenna is formed of the radiation conductor 52 and an upper ground conductor 53 short-circuited by a flank ground conductor 54 and increasing the area part of the radiation conductor 52 used for the whole antenna operation by adding the 2nd area part S2 on one surface side of the radiation conductor used for 2nd antenna operation to the 1st area part S1 on the other surface side of the radiation conductor 52 used for 1st antenna operation. The resonance frequency can, therefore, be decreased without making the length (e) and width (f) larger than those of a general type. Consequently, when the antenna 27 is put in operation at the same frequency as the general type, the overall size is reducible by the size equivalent to the decreased resonance frequency and the area of the antenna mounted on the portable radio device is reducible.

IPC: H02M7/5387
Filed: 1993-09-13
Abstract: PURPOSE:To suppress the circulating current of an AC power-supply apparatus without making a common-mode choke large and without removing a grounding wire. CONSTITUTION:First filter capacitors 51U, 51V are connected to the side of a power supply for reactors 11U, 11V which are inserted into individual phases on the input side of an AC power-supply apparatus, and ends, on the other side, of the individual filter capacitors are connected to a smoothing capacitor 2 which is installed in a DC intermediate circuit.

Title: Emergency cutoff valve
Inventor: NAMAKI TOSHIYUKI
IPC: G05D7/06
Filed: 1988-09-09
Abstract: PURPOSE:To execute excellent cutoff during the occurrence of an abnormal situation by a method wherein a steady change with a time of a flow rate is daily recorded by means of a measurement flow rate by a sensor for detecting a flow rate to determine a change with a time of a set flow rate, and a set flow rate is automatically changed with a time. CONSTITUTION:A setter A is formed such that a steady change with a time of a flow rate is actually measured daily, and a set flow rate is automatically changed with a time in direct proportion to a steady change with a time of a flow rate actually measured at a preceding day. Even when a steady change with a time of a flow rate is high or gradually changed, through variation of a set flow rate matching the change, a change based on a difference between a measurement flow rate of a sensor S for detecting a flow rate and a set flow rate is enough suppressed. This constitution reliably executes excellent emergency cutoff at a normally proper timing. A set flow rate determined by a computing circuit 18 is displayed by a display unit at each time zone.

Title: Manufacture of transmission type projection screen
Inventor: YOSHIOKA SHINPEI
IPC: G03B21/62
Filed: 1982-12-28
Abstract: PURPOSE:To form easily a pattern which is excellent in its light shielding property without requiring a wet process by exposing an adhesive agent from the surface opposite to the adhesive agent surface, eliminating an adhesive property of a condensing part, and thereafter, scattering a light shielding toner from on the observing surface, and sticking it to an unexposed part. CONSTITUTION:A propyrene sheet 4 is stripped off from a chromarin film 3, and a surface 7 of a photosensitive adhesive agent 6 is stuck to an observing surface side 2 of a screen. A chromarin film 9 of a condensing part of each lens of the screen is exposed by irradiating a beam from an opposite surface 8 to a film of the film provided with this chromarin film. After the exposure is ended, a ''Mylar'' film 5 is stripped off from the adhesive agent layer 6, the adhesive agent layer is exposed, and a chromarin toner 10 is scattered on this layer. Subsequently, the toner is stuck sufficiently onto the surface of the adhesive agent layer 6 with a pad, and therefore, the surface of the adhesive agent layer is wiped with cloth, and the toner adhering to the exposed part 9 and a surplus toner are removed. That is to say, since the exposure is executed before the light shielding toner is scattered, a sufficient effect can be given by an exposure of a short time. Also, the color tone and concentration of the light shielding toner can be selected freely.

Title: Autofocusing device
Inventor: FUKUOKA HIDESATO
IPC: G02B7/28
Filed: 1988-09-09
Abstract: PURPOSE:To keep a focusing state even while zooming is performed by controlling the driving speed of a focusing lens including an image-formation compensation function. CONSTITUTION:The autofocusing device is so constituted that the driving speed of the focusing lens 3 including the image-formation compensation function is controlled based on the information on the focal distance of a photographic lens, the information on focus detection and the information on the elapsed time related to a focus detection cycle while driving a variator lens 2 for variable magnification. Therefore, the control of a speed approximate to an ideal driving speed can be accomplished even in the case of not depending on the information on focus detection so much. Thus, the focusing state can be always kept even while zooming is performed without using a linking member such as a cam ring.
